Method of operating a revolver for shooting a projectile attached on the outside of the barrel thereof



July 1 1968 u. DUBINI METHOD OF OPERATING A REVOLVER FOR SHOOTING APROJECTILE ATTACHED ON THE OUTSIDE OF THE BARREL THEREOF Flled June 6,1966 N Hum ABSTRACT OF THE DISCLOSURE The method of operating a firearmincluding loading a blank cartridge into the firearm, placing acup-shaped projectile around the outside of the barrel of the firearmand firing the firearm to project the cup-shaped projectile.

The object of the present invention is to provide a method of operatinga firearm for projecting a cup-shaped projectile disposed on the outsideof the barrel of the firearm.

More particularly, the object of the present invention is the operationof a revolver characterized by being provided with a barrel adapted forshooting a cup-shaped bullet, which is closed at one end and seated onthe outside of said barrel, the powder or propelling charge being formedof a blank cartridge.

There-fore, the principle constituting novelty resides in the fact that,while projectiles are generally shot from the inside of the barrel, thefirearm of this invention carries a projectile externally enclosing thebarrel itself.

In view of this, the cylindrical portion bearing the projectile (whichwill be referred to as the barrel) may be of varying diameter and lengthaccording to the firearm to be used for definite purposes.

The accompanying drawing shows by way of example a revolver for use withthe present invention, and more particularly:

FIG. 1 is a side view of the revolver, wherein a bullet is schematicallyshown in a dash-line;

FIG. 2 is a detailed view of the revolver in FIG. 1 with a bullet formedof an empty cartridge-case disposed on the revolver barrel.

Referring to the figures, it will be appreciated that the revolver foruse with the present invention, has a barrel 1 with a cylindrical outersurface, which is adapted for shooting a substantially cup-shaped bullet2, closed at one end and seal-threaded or glidably engaged on theoutside of said barrel. The powder or propelling charge is given by aknown blank cartridge. Obviously, the closer the cartridge fits thebarrel, the more propelling force is provided as the gasses endeavor toescape. The word sealthreaded is used in the sense of the cartridgebeing tightly pressed on the barrel, but whether sealing is employed ornot, the invention operates satisfactorily. The bullet 2 glides over thebarrel for the full length of the barrel nited States Patent itself sothat the gas pressure operates for a longer time, i.e., corresponding tothe time that the open end of the bullet takes to leave the muzzle endof the revolve-r. In this way a stronger propelling force is obtainedand there- 5 fore a greater throwing distance, If the bullet has aninner diameter greater than the outer diameter of the barrel, there isno longer a gas-tight seal, and in such situations it is better to use ablank cartridge of greater power in order to obtain a good throwingdistance. Normally, the bullet is anticipated to be a cartridgecase 2 ofa shot hunting-cartridge. Said cartridge-case 2 is seal-threaded onbarrel 1, as shown in FIG. 2.

The major use of the revolver according to the invention is for shootingshot cartridge-cases as targets for new shots in replacement of aclay-pigeon, since hunters always have shot cartridge-cases at theirdisposal. However, other uses of the present invention are alsoanticipated, it being even possible to use cartridge-cases even of adifferent diameter and blank cartridges of a greater power.

It is anticipated, for example, that a firearm for use with the presentinvention could serve for sporting targetfiring since the cartridge-casebeing shot therefrom may be frontally provided with a suction cup or atip.

Another use of the present invention is for projecting lightfishing-lines to significant distances by attaching the fishing-line tothe empty cartridge-case, as illustrated in phantom in FIG. 1, so thatit would unhook on contacting the water.

Obviously, the shooting power may be adjusted by us- 30 ing more or lesspowerful blank cartridges; moreover, said shooting power may be modifiedby narrowing or by enlarging the cartridge chamber within the firearmbarrel; under the same cartridge power, by enlarging the cartridgechamber, pressure and hence also throwing distance will be reduced.

What is claimed is:

1. The method of operating a firearm for projecting a cup-shapedprojectile therefrom comprising the steps of loading said firearm withat least one blank cartridge, inserting the barrel of the firearm intothe cup-shaped projectile and firing the firearm.

2. The invention of claim 1 wherein said cup-shaped projectile has aline attached thereto.
